component-builder2 Build Status

Another version of component’s builder. Some differences:

  • Everything is streaming!
  • Split into multiple builders
  • Much leaner require implementation
  • Handles newer features like globs
  • Fixes a lot of issues with the previous builder

Depends on:

  • resolver - resolved dependency tree
  • flatten - flatten the dependency tree to create a build order
  • require2 - this builder’s require() implementation.
  • manifest - unglobs components’ fields and creates file objects suitable for plugins
  • builder-es6-module-to-cjs - the included ES6 -> CJS plugin

You may be interested in:

  • bundler - create multiple bundles from the resolved dependency tree

Installation

npm install --save-dev component-builder

NOTE: Don’t use the npm repo component-builder2 anymore. You get both versions component/builder.js and component/builder2.js at this npm repo now: component-builder

Example

var fs = require('fs');
var resolve = require('component-resolver');
var build = require('component-builder');

// resolve the dependency tree
resolve(process.cwd(), {
  // install the remote components locally
  install: true
}, function (err, tree) {
  if (err) throw err;

  // only include `.js` files from components' `.scripts` field
  build.scripts(tree)
    .use('scripts', build.plugins.js())
    .end(function (err, string) {
      if (err) throw err;
      fs.writeFileSync('build.js', string);
    });

  // only include `.css` files from components' `.styles` field
  build.styles(tree)
    .use('styles', build.plugins.css())
    .end(function (err, string) {
      if (err) throw err;
      fs.writeFileSync('build.css', string);
    });

  // only copy `images` to the build folder
  build.files(tree)
    .use('images', build.plugins.symlink())
    .end(); // callback optional
})

Builders

There are three types of builders:

  • scripts - streaming builder for the Javascript file.
  • styles - streaming builder for the CSS file.
  • files - channel-based builder for everything else, which generally means copying or symlinking

You’ll also want to read docs on builder, which all three builders above inherit from.

See the documentation for more information on each.
